CARTRIDGE.

To all whom 'it may concern.'

Be it known that I, GEORGE A. FINSTER, a citizen of the United States, residing at Schenectady, and State of New `York, have inyentedlcertain new and, useful Improvements in Cartridges; and I do declare the following to be a full, clear, and exact description of the in- 'vention, such as will enable othersy skilled in 'the art to which it4 ap'pertains to make and use the same.

. This inventiongrelates to an improved explosive, which may be used in either large or V it coming in violent contact with small projectiles.

explosive for use in projectiles of various sizes which will not explode until an object. x In the accompanying drawings,-.- Figure 1 represents a lonffitudinal section of a cartridge constructed in accordance with this invention; Fig. 2 represents a transverse section ofy a cartridge showing a slightly modified form of the invention; Fig. 3 re reseiits a similar' view of another modification'.

In the embodiment illustrated in Fig. 1 a cartridge is shown comprising' a shell 1, preferably of steel coated with shellac to revent rusting thereof, and having a frangibA e partition 2, preferably of glass, arranged transversely thereof and 'connected therewith by putty 3 or in any othersuitable manner, whereby it may be liquid-tight. ble partition divides the shell into two compartments 4 and 5.

`lled with metallic sodium, preferably having a small amount of kerosene oil mixed therewith to prevent the sodium from melting in hot climates. l

The two members may be connected by putty or cement 3, or in any other suitable manner.

i other s'uita The compartment 4 is'lled with water or The object/of the invention is to provide- -a cheap Specication of Letters Patent. Application filed August 16.19Q'7. eria1N.388.912.

in the county of SchenectadyV This frangi- The compartment 5 is v le liquid which coming in contact with the sodium will cause" it to explode v between the meeting ends of Patented Feb. 4, -1908.

tion 6 is shown arranged longitudinally of the cartridge with` the water and sodium 'compartments arranged on opposite sides thereof. v

In Fig. 3 iss-hown a hollow ball composed of two-members 7 and 8 separably connected, the member 7 having an annular internally screw-threaded Harige 9 adapted to engage an externally screw threaded flange 10 ormed on the member 8. The member 7 has a covering 11 of material arranged across the face which is adapted to be connected with the other member',v and the compartment so formed is illed with water. The other member 8 is filled with metallic -sodium and operates in the same manner as the above described form.

In the use of this invention when the projectile comes in contact with a ship or other object the glass partition is broken and the water mixes with the lmetallic sodium, thereby causing a terrific explosion, damaging and injuring everything adjacent thereto;A

I claim as my invention 1. An ex losive projectile composed of two separab y connected members having a -frangible partition arranged between them 'at the point of connection,.one'member containing an explosive compound and the other means for exploding said compound when.

coming in contact therewith.

2. An explosive projectile composed' of two separably connected members, one of which has an internally screwthreaded flange provided on-its meeting face and the other an externally screwthreaded flange for coperation with the flange on the other member, anda frangible partition arranged said members.

In testimonyl whereof I4 have hereunto set my hand in presence of two nesses.
